It was reported that the procedure was to treat a lesion in the mid superficial femoral (sfa) artery with moderate tortuosity and heavy calcification.It was noted that the sfa was occluded and there was a lot of calcification.The 6 x 60 mm armada balloon catheter was prepared per the instructions for use and advanced to the lesion without issue.The balloon was inflated two times; however, this did not manage to suppress all the calcification.During the third inflation with the balloon, a balloon rupture occurred.The inflation pressures are unknown, but noted to be not high.An attempt was made to remove the armada balloon catheter; however, resistance was noted with the sheath, and the balloon began to bunch up on the sheath.When the balloon catheter was pulled more, the distal end of the balloon broke loose from the balloon catheter.The entire balloon was separated from the catheter.The separated portion traveled distal in the sfa.The balloon catheter was then removed and a cut down procedure was performed.Forceps were used to remove the distal portion of the balloon catheter from the anatomy.The patient was sent to revascularization for treatment of the lesion, and needed to stay for two days in the hospital instead of an immediate discharge.It was noted that the patient developed a wound infection at the cut down site which is partially necrotic and currently being treated with antibiotics.No additional information was provided.
